Abstract
Abrasive Jet Machining (AJM) is a new concept in blast processing. The mechanism involves the controlled injection of a fine abrasive medium onto a substrate material using compressed air as a carrier. Conventional methods of blast processing have commonly been used for ground works or for deburring. They can also be used to create decorative characters or geometric patterns on a surface. With these techniques, the target area is selectively masked and is then blast processed over the mask so that the desired patterns are produced. On the other hand, the AJM technique uses a new design of nozzle to precisely control the volume of abrasive, and thus enables us to achieve abrasion in specific desired areas without the use of masks. In this presentation, we will first explain the theory behind the AJM technique and will then introduce some examples of the process.
